Air Suspension Components Star Parts Catalog has been updated to show individual service parts for the compressor assembly. This will allow service technicians to repair the root cause without over repairing the system. Replace only the part deemed failed by the diagnostics performed. Individual parts include: - Compressor - Valve block - Individual hoses - Temp sensor - Shield - Air line clips NOTE: in most situations when a new compressor is needed, the compressor as a separate part is the correct repair, and the assembly would not be required.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Part Description: RHR Radio Issue Description: Issue 1: While performing RHR radio reflash (software update), on rare occasions, the flash can fail to properly update the radio resulting in the radio running in Emergency IFS mode. This error condition can occur due to interrupting the software update, background radio operations interfering with the reflash process, etc. The radio will reboot, but with limited functionality (examples may include but are not limited to: NAV, Voice Recognition, Bluetooth, or AUX jack are inop, no available space shown on HDD, etc.). The radio can still be properly updated by simply reinserting the software update disc and performing the reflash procedure again

The failure pattern owners describe
The 2011 Jeep Wrangler suspension problems cluster around a violent shaking condition called "death wobble"—violent front-end oscillation at highway speeds (35-75 mph) triggered by bumps, sometimes so severe owners lose steering control. Owners report the condition stops only when they pull over and stop completely.
The root cause appears to be factory-installed incorrect fasteners: 14MM bolts were used instead of 9/16-inch shoulder bolts in track bar bushings and lower control arms. The threaded bolts cut into the rubber bushings, enlarging the holes and allowing movement that cascades into death wobble. By the time it's caught, bushings are damaged and full suspension component replacement (track bars, control arms) is needed.
Beyond death wobble, owners report loose anti-sway bar fasteners as early as 6,000 miles, rear axle seal failure and bearing wear around 46,000 miles causing rear vibration, and defective springs that cause shaking even after initial brake component repairs. One owner's sway bar disconnect motor connection allowed water intrusion after a car wash, killing the TIPM and preventing restart. A rear suspension instability issue causes the rear end to jump and flop when hitting bumps or braking hard.
Jeep issued a recall for loose suspension fasteners on 2010-2011 models, but not all affected VINs were included. Many dealerships could not diagnose or replicate death wobble, leaving owners afraid to drive their vehicles.

Failure modes owners describe
Death Wobble - Front End Oscillation
Violent shaking and flutter of the front suspension (ball joints, track bars, lower control arms) triggered by bumps or specific highway speeds. Owners report the steering wheel shakes severely, loss of control at highway speeds, and the condition stops only when the vehicle comes to a complete stop. This is attributed to loose or damaged front suspension components.
When: As low as 22,000 miles; occurs at speeds between 35-75 mph, typically triggered by bumps or uneven road surfaces
Symptoms owners cite: Violent steering wheel shaking; Front end oscillation/flutter; Loss of vehicle control; Suspension vibration at highway speeds; Condition resolves when vehicle stops
Repairs/costs cited: Narrative #1 indicates track bars, lower control arms, and related bushings require replacement; some owners report suspension component replacements attempted; some dealerships unable to diagnose or replicate the condition
Recalls/TSBs owners mention: Jeep issued a recall for loose suspension fasteners on 2010-2011 models, though some affected VINs were reportedly excluded; some narratives reference the existence of a sticky post on Wranglers Forum titled 'The Importance of Changing Out Stock Bolts' with over 12,000 views and 300+ posts suggesting a known community workaround
Incorrect Bolts in Track Bar Bushings and Lower Control Arms
Factory installation of 14MM bolts instead of the correct 9/16 inch shoulder bolts in track bar bushings and lower control arms. Threaded bolts were used instead of proper shoulder bolts (smooth shank with threads only at bottom), causing the threads to cut into the rubber bushings and enlarge the holes, reducing clamping force and leading to movement and wear.
When: Present from assembly; damage discovered at various mileages (22k-140k miles reported)
Symptoms owners cite: Worn bushings with visible cutting/thread damage inside; Loosened fasteners; Eventual death wobble as bushing wear progresses
Repairs/costs cited: Replacement bolts alone insufficient; track bars, lower control arms, and related suspension components require replacement once bushing damage occurs
Loose Anti-Sway Bar Fasteners
Upper anti-sway bar fasteners on the front suspension come loose from the factory or early in vehicle life. One owner discovered the oil drain plug also loose at first service, raising concerns about general fastener quality.
When: As early as 6,000 miles
Symptoms owners cite: Clunking noise at low speeds; Loose fasteners detectable by hand torquing
Repairs/costs cited: Owner re-torqued to spec; however, Jeep's recall for loose suspension fasteners excluded this vehicle's VIN despite the condition being present
Recalls/TSBs owners mention: Jeep issued recall for loose suspension fasteners on 2010-2011 models, but not all affected VINs were included
Rear End Vibration and Bearing/Seal Failure
Rear axle vibration at highway speeds caused by failing rear axle seal and bearing wear. One owner reported rear axle seal leakage requiring replacement of bearing, wheel seal, brake pads, emergency brake shoes, and parking brake shoes.
When: 46,151 miles
Symptoms owners cite: Rear end vibration at highway speeds (70 mph reported); Rear axle seal leakage
Repairs/costs cited: Rear axle seal, bearing, brake pads, emergency and parking brake shoes, and wheel seal replaced
Violent Vibration on Hard-Surface Roads - Persistent After Repairs
Vehicle vibrates violently on hard asphalt roads between 35-75 mph. Despite multiple dealer service visits and repairs, the condition recurred repeatedly and was not permanently resolved. Root cause appears suspension-related but specific components not identified in narrative.
When: 46,000 miles (approximate mileage when reported)
Symptoms owners cite: Violent vibration on hard-surface roads; Vibration across broad speed range (35-75 mph); Recurring failure despite multiple repair attempts
Repairs/costs cited: Vehicle taken to dealer multiple times and repaired, but failure persisted
Recalls/TSBs owners mention: Manufacturer notified; repairs attempted but unsuccessful
Sway Bar Disconnect Electrical Failure - Water Intrusion
Sway bar disconnect motor connection is not water-tight. Water infiltrated the connection after a car wash, causing the TIPM (Totally Integrated Power Module) to fail. The sway bar disconnect light flashed, and subsequently all dashboard lights flashed before the vehicle shut off and would not restart.
When: Occurs after car wash; narratives mention this also happens during rain storms
Symptoms owners cite: Sway bar disconnect light flashing; All dashboard lights flashing; Vehicle shutdown and failure to restart; TIPM failure
Repairs/costs cited: TIPM was fried with disconnect motor and required replacement
Suspension Springs Defective
Vehicle exhibited violent shaking and abnormal noise at 60 mph. Initially diagnosed as rotor and brake caliper issues and repaired, but failure recurred. Upon re-diagnosis, springs were identified as defective.
When: 88,000 miles
Symptoms owners cite: Violent shaking; Abnormal noise; Failure at 60 mph
Repairs/costs cited: Front driver side rotor and brake caliper initially replaced; springs then identified as needing replacement
Recalls/TSBs owners mention: Manufacturer notified
Rear Suspension Instability - Jumping and Flopping
Vehicle jumps and the rear end flops to one side when hitting small bumps or during hard braking, suggesting rear suspension geometry or component issues. Narrative mentions suspension parts are all new or newer, suggesting a prior failure and incomplete repair.
When: Persistent over 30,000 miles of ownership
Symptoms owners cite: Rear end jumping when hitting bumps; Rear end flopping to one side; Hard braking causes same jumping motion
Repairs/costs cited: All suspension parts reportedly new or newer, indicating prior repair work
